Abstract
Description
- Controller Pilot Data Link Communication (CPDLC) provides the ability for pilots and Air Traffic Control (ATC) to communicate digitally via text messages. One of the main benefits of this form of communication is limiting congestion on voice communication frequencies in busy airspace. However, one positive benefit voice communication may provide is the “party-line” concept, which allows pilots to monitor voice communications between ATC and other aircraft tuned to the same frequency. This valuable information broadcast via voice may allow pilots to increase situational awareness of nearby activity.
- For example, by listening to other communications, pilots may approximate a position of a nearby aircraft, become aware of a current weather situation along their route of flight, obtain turbulence reports and overhear optimal altitudes for smoother rides, increase awareness of deviation directions around weather systems, and learn about delays due to ATC congestion, weather, or other reasons.
- Unfortunately, current CPDLC communications are limited to a one-to-one form of communication between ATC and an aircraft. This limitation effectively eliminates the pilot's ability to increase awareness relating to nearby traffic and the benefits thereof.
- Therefore, a need remains for a system and related method which may overcome these limitations and provide an ability for increasing mutual support between aircraft building pilot situational awareness via a display of communications between nearby aircraft and a controlling authority.
- In one aspect, embodiments of the inventive concepts disclosed herein are directed to a system for mutual display of Controller Pilot Data Link Communication (CPDLC) messages. The system may comprise a radio configured for sending and receiving radio frequency data signals, an antenna operatively coupled with the radio, the radio and the antenna functional on a first aircraft. To control the function, the system may include a controller operatively coupled with the radio, a CPDLC display, and a pilot display. The controller may function with a tangible, non-transitory memory configured to communicate with the controller, the tangible, non-transitory memory having instructions stored therein that, in response to execution by the controller, cause the controller to execute functions associated with the operation of the system.
- The system may function to receive a first CPDLC inbound data message, the first CPDLC inbound data message addressed to the first aircraft. The system may display the first CPDLC inbound data message on each of: the CPDLC display and the pilot display. The system may receive a CPDLC outbound data message from a pilot interface aboard the first aircraft, the CPDLC outbound data message addressed to a data authority. The system may display the CPDLC outbound data message on each of: the CPDLC display and the pilot display, and send the CPDLC outbound data message to the radio. The system may receive a second CPDLC inbound data message sent from the data authority and display the second CPDLC inbound data message on the pilot display. The system may receive a third CPDLC inbound data message sent from a second aircraft and display the third CPDLC inbound data message on the pilot display.
- A further embodiment of the inventive concepts disclosed herein may be directed to a method for CPDLC chat. The method may comprise, at a
step 502, receiving a first CPDLC inbound data message, the first CPDLC inbound data message addressed to a first aircraft. This first inbound CPDLC message may be directive for the flight crew of the first aircraft to execute a maneuver. To ensure the flight crew receives the first inbound message, the method may display, at astep 504, the first CPDLC inbound data message on each of: a CPDLC display and a pilot display. To ensure all message traffic associated with the first aircraft is available to the flight crew, the method may include, at astep 506, receiving a CPDLC outbound data message from a pilot interface aboard the first aircraft, the CPDLC outbound data message addressed to a data authority and, at astep 508, displaying the CPDLC outbound data message on each of: the CPDLC display and the pilot display. The method may include, at astep 510, sending the CPDLC outbound data message to the radio. - Additionally, to offer situational awareness to the pilots of the first aircraft, the method may include, at a

FIG. 1 , a diagram of an environment in which CPDLC chat may operate in accordance with an embodiment of the inventive concepts disclosed herein is shown. Generally, embodiments of the inventive concepts disclosed herein may restore an ability for pilots in each aircraft to monitor other aircraft communications with Air Traffic Control (ATC) when using CPDLC. - An
environment 100 within which embodiments of the inventive concepts disclosed herein may operate may include airspace controlled by a Current Data Authority (CDA) 130 with an associatedCDA antenna 132. TheCDA 130 may communicate with and control each aircraft within airspace bounded by its geographical area of responsibility (AOR). In order to enter the specific airspace of the CDA, each aircraft must establish data link communications with the CDA before entering the CDA AOR. Here, pilots of anownship aircraft 110 have established communication with the CDA and are transiting the airspace of the CDA. In addition, aparallel aircraft 114 and anopposite aircraft 112 are nearby theownship aircraft 110 where CPDLC communications between the CDA and these aircraft may be of interest to theownship aircraft 110 pilots for increased pilot situational awareness. - Communications between the CDA and each aircraft 110-114 may be direct via a line of sight communications link or via satellite communications via a
communications satellite 134. The data associated with the CPDLC signal is the same regardless of the method of transmission and reception. - Enroute to a destination, the
ownship aircraft 110 may transit a plurality of AORs each with a data authority tasked with aircraft management and separation. Here, a Next Data Authority (NDA) 140 with associatedNDA antenna 142 may be next in line for theownship aircraft 110 to contact and remain under positive control. For example, Gander Area Control Center (ACC) with an identifier of CZQX may function as a CDA in the north Atlantic. As theownship aircraft 110 may fly east across the Atlantic, the NDA may include Shanwick Oceanic control with an identifier of EGGX. Before entering the airspace controlled by Shanwick, the ownship aircraft must establish a CPDLC link with Shanwick. - Referring now to
FIG. 2 , a diagram of a system for CPDLC chat in accordance with an embodiment of the inventive concepts disclosed herein is shown. A system for CPDLC chat 200 may enable pilots of one aircraft to read communications between a CDA or NDA and all aircraft of interest. The system for CPDLC chat 200 may be comprised of a multi-function display (MFD) 220 sited on a flight deck display system which may be configured to display various CPDLC communications between a data authority such as aCDA 130 andownship aircraft 110 as well asother aircraft controller 230 coupled with aradio 234 and associatedantenna 236. - In one embodiment of the inventive concepts disclosed herein, the system for CPDLC chat 200 may employ the
MFD 220 to provide the flight crew with a real time CPDLC chat log 222 of messages being sent and received by theCDA 130. Additionally, the flight crew may opt to monitor CPDLC messages sent and received by theNDA 140. - In one embodiment of the inventive concepts disclosed herein, the system for CPDLC chat 200 may exist separately from (and may not replace) the traditional
onboard CPDLC system 250 on theownship aircraft 110. Thistraditional CPDLC system 250 may be functional to receive and respond to uplink messages and transmit downlink messages. Suchtraditional CPDLC system 250 may include thecontroller 230 with an associatedmemory 232, theradio 234, theantenna 236, and a CPDLC display/pilot interface 210 offering pilot input commands as well as displayingownship data 240. In embodiments, the radio may be associated with one or more systems onboard theaircraft 110 or function as a dedicated CPDLC radio. - In another exemplary embodiment, the system for CPDLC chat 200 may replace a currently installed
traditional CPDLC system 250. In this manner, the flight crew may interact with the system for CPDLC chat 200 using similar methods as with atraditional CPDLC system 250. The system for CPDLC chat 200 may receive from the flight crew each outbound CPDLC message as well as inbound messages addressed to theownship aircraft 110 andaircraft 112 114 andCDA 130NDA 140 the ownship pilots may wish to monitor. - In one embodiment of the inventive concepts disclosed herein, the system for CPDLC chat 200 may not only display message data from
other aircraft 112 114 and theCDA 130 andNDA 140, but also receive messages transmitted and received by theownship aircraft 110. The system for CPDLC chat 200 may highlight (e.g., color, bold font, backlight etc.) these messages in theCPDLC chat log 222. In this manner, the pilot of theownship aircraft 110 may easily recognize CPDLC messages addressed to theownship aircraft 110 and intended for immediate action. - In one embodiment, an inbound message addressed to and received by the
ownship aircraft 110 may be a first inbound type of CPDLC data message. A message sent by theCDA 130NDA 140 and addressed to asecond aircraft radio 234 may be considered a second inbound type of message. While a third inbound type of CPDLC message may be considered a message originated at thesecond aircraft CDA 130NDA 140 but also received by theradio 234. An outbound message may be considered as being one that is originated by the pilots onboard theownship aircraft 110. - In one embodiment of the inventive concepts disclosed herein, display of each of the first, second, and third CPDLC inbound and the outbound data messages on the pilot display may include a display of an associated time stamp, a name of the sender, a name of the receiver, and a text of the message body.
- The
CPDLC chat log 222 may offer enhanced pilot awareness to each pilot using the system forCPDLC chat 200. For example, the system for CPDLC chat 200 may display on theMFD 220 the pilot selectable set of data from which the pilot of the ownship aircraft 110 (here, RC007) may display. As eachnearby aircraft 112 114 communicates with ATC (here, Chicago Air Route Traffic Control Center (ARTCC)), the system for CPDLC chat 200 displays theCPDLC chat log 222 to theownship aircraft 110 pilots on theMFD 220. Here, the pilots of RC007 may learn that AA524 is deviating for weather and DL32 is climbing to FL370. Prior to implementation of the inventive concepts disclosed herein, the pilots of RC007 would be oblivious to this information. - In one embodiment of the inventive concepts disclosed herein, the system for CPDLC chat 200 may receive a CPDLC inbound data message from the
radio 234 and send the CPDLC inbound data message to a CPDLC display/pilot interface 210, the CPDLC inbound data message addressed to thefirst aircraft 110. Here, thecontroller 230 may be configured to receive a CPDLC outbound data message from the CPDLC display/pilot interface 210 and send the CPDLC outbound data message to theradio 230, the CPDLC outbound data message addressed to a data authority (e.g., the CDA or the NDA). - The associated
memory 232 may comprise a tangible, non-transitory memory configured to communicate with the controller, the tangible, non-transitory memory having instructions stored therein that, in response to execution by the controller, cause the controller to preform function associated with the system forCPDLC chat 200. Specifically, the system for CPDLC chat may receive a CPDLC inbound data message addressed to a second aircraft. Here, the second aircraft may be a nearby aircraft such as theparallel aircraft 114 as well as theopposite aircraft 112. The system for CPDLC chat may display the received CPDLC inbound data message addressed to the second aircraft on the pilot display. Here, the pilot display may include a MFD, heads up display (HUD) and additional displays designed for pilot viewing. - The system for CPDLC chat may also receive a CPDLC inbound data message sent from the
second aircraft 112 114 and addressed to thedata authority 130 140 and display the received CPDLC inbound data message addressed to the data authority on the pilot display. In this manner, the system for CPDLC chat 200 may function as a source of all CPDLC data messages selected by the pilots of theownship aircraft 110 for display in theownship aircraft 110 flightdeck display MFD 220. - In one embodiment of the inventive concepts disclosed herein, the
MFD 220 may comprise an installed display onboard the aircraft as well as a hand-held tablet device configured to display theCPDLC chat log 222. It is contemplated herein, the hand-held tablet device may receive wireless data from theownship aircraft 110 traditional CPDLC system via an onboard wireless network as well as via an individual tablet radio connection with theCDA 130. - Further, system for CPDLC chat 200 may display an aggregate of messages between ATC and all aircraft may be available from data service providers, such as ARINC. Contemplated herein, the system for CPDLC chat 200 may receive and display all messages to and from the
CDA 130 and theNDA 140, as well as any data authority the pilot may select. In one embodiment of the inventive concepts disclosed herein, the system for CPDLC chat 200 may function to receive and display CPDLC data messages sent from eachdata authority CDA 130NDA 140 selected by the pilot. In this manner, theCDA 130 may function as a broadcast center for each CPDLC data message it may send and receive and broadcast (repeat) each transmission to all participating aircraft limited by pilot selection. - These messages may be streamed to the aircraft via line of sight radio frequency data streams as well as satellite communication data streams. As the industry moves towards “connectionless” CPDLC where an aircraft may not be required to explicitly connect or login with a CDA to exchange information, the system for CPDLC chat 200 may function to receive and display each message to the flight crew. Also, should an industry migrate toward an Internet Protocols Suite (IPS) based network technology, system for
CPDLC chat 200 is configured to receive and display CPDLC messages between various ground stations and aircraft. The system for CPDLC chat 200 will allow each pilot to determine a set of aircraft andCDA 130NDA 140 to which the system for CPDLC chat 200 may listen. - For example, on a transatlantic ocean track, pilots of an
ownship aircraft 110 may employ the system for CPDLC chat 200 to monitor communications between each aircraft on their assigned track regardless of the range at which each aircraft is distant from theownship aircraft 110 or direction of flight. In this manner, the pilots of theownship aircraft 110 may gain situational awareness aboutconditions - As the system for
CPDLC chat 200 is a situational-awareness tool, it may be configured to be displayed as a Multi-Function Format on an avionic display or on a tablet/Electronic Flight Bag (EFB) application, such as “ARINC Direct.” In addition, the CPDLC log 222 may be displayed on any flight deck display system that incorporates CPDLC, in addition to an Information Management Services (IMS) ARINC Direct tablet application. - Referring now to
FIG. 3 , a diagram of a flowchart for CPDLC chat exemplary of an embodiment of the inventive concepts disclosed herein is shown. Alogic flow 300 of the system for CPDLC chat 200 may include receiving a first, second and third inbound CPDLC message at astep 302. In review, the message types here may include: - Outbound—Originated by
ownship 110; - First Inbound—Originated by
CDA 130 and addressed toownship 110; - Second Inbound—Originated by
CDA 130 and addressed toother aircraft 112 114; and - Third Inbound—Originated by
other aircraft 112 114 and addressed to anydata authority CDA 130NDA 140. - Each type of inbound CPDLC message may be addressed to any entity within an area selected by the pilot (e.g.,
parallel aircraft 114,CDA 130,NDA 140, all entities within a specific range). At astep 304, the logic may query if the inbound CPDLC message is associated (e.g., a first type of inbound) theownship aircraft 110. If the result is negative, the logic may flow to astep 310 with displaying the CPDLC message on theMFD 220. - Should the result of
query 304 be positive, the logic may flow to astep 306 with display of the CPDLC message on MFD in highlight to ensure the pilots of theownship 110 may discriminate the ownship messages from the list within theCPDLC chat log 222. At astep 308 the logic may further display the inbound ownship message on aCPDLC display 210. - Referring now to
FIG. 4 , a diagram of available settings for a method for CPDLC chat exemplary of one embodiment of the inventive concepts disclosed herein is shown.Available settings 400 may be optionally selectable by the flight crew to ensure desired entities are monitored for maximum situational awareness. - Contemplated herein, the MFD 220 (and additional display types) may include capability for pilot interaction via a touch screen user interface capable of selection of various settings associated with the system for
CPDLC chat 200. For example, alog page 410 may include the CPDLC chat log 222 while aCDA page 412 may include a list of CDA from which the pilot may select to monitor. Also, arange page 414 may include a selectable geographical range AND Track from which the pilot may monitor communication (e.g., 100 MN, 200 NM, 500 NM, TRACK A) range of monitoring. - The system for CPDLC chat 200 may offer a display filtered by a pilot selectable limitation in range, track, aircraft type, and altitude. Also, a limitation in messages forward of the
ownship aircraft 110 since theownship aircraft 110 is tracking in a forward direction. Messages forward of theownship aircraft 110 and beyond line of sight may be of particular interest to theownship aircraft 110 pilots. - Referring now to
FIG. 5 , a diagram of a method for CPDLC chat in accordance with one embodiment of the inventive concepts disclosed herein is shown. Amethod flow 500 for CPDLC chat may include, at astep 502, receiving a first CPDLC inbound data message, the first CPDLC inbound data message addressed to a first aircraft. Astep 504 may include displaying the first CPDLC inbound data message on each of: a CPDLC display and a pilot display. Astep 506 may include receiving a CPDLC outbound data message from a pilot interface aboard the first aircraft, the CPDLC outbound data message addressed to a data authority and astep 508 may include displaying the CPDLC outbound data message on each of: the CPDLC display and the pilot display. To transmit the message, astep 510 may include sending the CPDLC outbound data message to the radio. - To display messages from additional entities, a
step 512 may include receiving a second CPDLC inbound data message sent from the data authority while astep 514 may include displaying the second CPDLC inbound data message on the pilot display. Astep 516 may receive a third CPDLC inbound data message sent from a second aircraft and astep 518 may include displaying the third CPDLC inbound data message on the pilot display. - As will be appreciated from the above description, embodiments of the inventive concepts disclosed herein may provide an ability for increasing mutual support between aircraft building pilot situational awareness via a display of communications between nearby aircraft and a controlling authority.
- It is to be understood that embodiments of the methods according to the inventive concepts disclosed herein may include one or more of the steps described herein. Further, such steps may be carried out in any desired order and two or more of the steps may be carried out simultaneously with one another. Two or more of the steps disclosed herein may be combined in a single step, and in some embodiments, one or more of the steps may be carried out as two or more sub-steps. Further, other steps or sub-steps may be carried in addition to, or as substitutes to one or more of the steps disclosed herein.
- From the above description, it is clear that the inventive concepts disclosed herein are well adapted to carry out the objects and to attain the advantages mentioned herein as well as those inherent in the inventive concepts disclosed herein. While presently preferred embodiments of the inventive concepts disclosed herein have been described for purposes of this disclosure, it will be understood that numerous changes may be made which will readily suggest themselves to those skilled in the art and which are accomplished within the broad scope and coverage of the inventive concepts disclosed and claimed herein.
